As usual the single most important advice is missing:

* Don't have (more than one) child. *

We could build an everlasting eden for humankind if we could persuade everybody to limit themselves to one child for couple for the next two or three generations and then switch to two children for couple.

Lacking that we are doomed to damnation.

No you couldn't. Instead you would doom billions to death and starvation, because during the transition time you need young people to support the old.

And who exactly would operate this "everlasting eden"?

Just about every single technology we have only exists because there are so many people in the world, which makes the cost of the item bearable.

Overpopulation is a menace and family planning is the only viable solution. Two or three billions of healthy, nourished, educated human beings are more than enough to substain our economical, social and scientific structure.

Why two or three and not twenty or thirty, if we're specifying that they're healthy and educated? :) Overpopulation (in the sense of too many meat humans) is no longer particularly relevant to our future; simple copying seems likely to be more important.

"Instead you would doom billions to death and starvation, because during the transition time you need young people to support the old."

Not if we kill them when they reach the age of 30.
